". sn w AND 10E nisrosmc APPARATUS I My invention relates to snow and ice disposing apparatus, and included in the objects of my invention are:

First, to provide an apparatus of this class which may be mounted on a truck and is adapted to receive ice and snow supplied by mechanical loading devices and melt such ice or snow for discharge as water into sewer mains.

Second, to provide an apparatus for the disposal of iceor snow, which is particularly efiicient in its operation in that a minimum amount of heat energy is required and it is economical of manufacture.

Third, to provide an apparatus of this class wherein the ice or snow is broken into chunks of sufiicient size to flow through and around a bank of heated pipes, in such a manner, that the ice or snow is not only melted by Contact with the pipes but is also washed and melted by heated water produced by the melting of ice or snow above.

With the above and other objectsin view as may appear hereinafter, reference is made to the accompanying drawings, in which:

Figure l is a side view of a truck equipped with my snow and ice disposing apparatus.

Figure 2 is an enlarged plan view of my apparatus.

Figure 3 is a rear end view thereof with one of the access doors open and the other broken away.

Figure 4 is an enlarged sectional view through 4--4 of Figure 3.

Figure 5 is an enlarged fragmentary sectional view through 55 of Figure 4.

My snow and ice disposing apparatus is adapted to be mounted on the bed of a truck T and includes a base I on which is mounted an outer shell or jacket 2, which must be rectangular or square in plan and provided with doors 3 at its rear side. Within the outer shell 2 is an inner shell 4. The upper end of the inner shell is open and provided with an outwardly flanged hopper rim 5.

The inner shell is provided with banks of horizontal tubes Gwhich extend between the front and rear walls of the inner shell. The tubes are open at their extremities and burners l are fitted in their rearward ends, that is, the ends adjacent the doors 3. The space between the front sides of the shells 2 and 4, as well as the two lateral sides, forms a discharge passage 8 for the products of combustion issuing from the forward ends of the tubes 4. The space between the upper margins of the two shells is closed s-liiere fi daleCa f, V v ag u ea gag a 3, 1950, Serial No. ragga;

2 Claims. (Cl. ce-res s 2 except for outlet or vent ports 9 provided adjacent the rear corners of the shells.

The forward walls of the outer shell preferably include an insulation panel [0, and forwardly of this wall are mounted one or more fuel supply tanks ll. These tanks may be arranged to accommodate oil or gas as desired. Lines I2 from the tanks pass through the rearwardly extending portions of the discharge passage 8 and communicate with the burners 1.

The bottom of the inner shell 4 is provided with a drain pan l3 having a water outlet I4 controlled by a valve I5 located at one side of the truck bed. The rear wall of the inner shell below the burners is provided with a clean-out door It.

It is particularly advantageous to provide on the upper bank of tubes 6, rows of spikes or prongs H. The prongs act to break up the snow or ice into chunks which fall or wedge between the tubes and are thereby caused to melt. Such chunks as may fall downwardly between the] tubes collect on the pan and are melted by contact with the lower banks of tubes, and are also washed and melted by heated water dripping from the melting of other chunks of snow or ice wedged between the tubes above.

Having fully described my invention, it is to be understood that I do not wish to be limited to the details herein set forth, but my inven tion is the full scope of the appended claims.

I claim:

1. A snow and ice melter, comprising a rectangular bin for receiving snow and ice; 2. plurality of heating tubes arranged in rows and columns and traversing said bin, said tubes being open at their extremities externally of said bin; a burner unit for each tube including a burner nozzle directed into one end of each tube to direct a flame therethrough; a heater jacket covering and common to the opposite ends of said tubes and extending along the sides of said bin; said heater jacket having outlet ports for the products of combustion from said burners located adjacent the burner ends of said tubes, a fuel supply means; a fuel pipe for each row of burners extending from said fuel supply means through said heater jacket and across said row of burner units.

2. A snow and ice melter, comprising: a rectangular bin-like structure adapted to receive snow and ice; a shell surrounding and spaced from the sides of said structure, one side of said shell having access doors exposing a corresponding side of said bin-like structure, the remaining 3 sides of said shell defining with said bin-like structure a heater jacket, having upwardly directed discharge ports at the sides of said shell adjacent said access doors; heating tubes arranged in rows and columns and extending across said bin-like structure from the side adjacent said access doors to the opposite side; a burner unit directedinto each of said tubes and accessible through said access doors; a fuel supply means beyond the side of said shell opposite from said access doors; and a fuel pipe for each row of burners extending from said fuel supply means through said heater jacket and across a row of said burner units.
